Many surgical procedures are now performed using the techniques of minimally invasive surgery (MIS), in which the surgeon manipulates instruments inserted into the patients through small incisions. In MIS, the surgeon has no direct contact with internal body parts. Applying an optimal force and torque via the instruments is necessary to conduct an operation without causing any damage to the int...

We show the possibility to improve the measurement sensitivity of a weak force by using massive probes in an entangled state. This latter can be achieved by exploiting radiation pressure effects. 03.65.Ta, 42.50.Vk, 03.65.Ud Typeset using REVTEX 1 Since the original formulation of quantum mechanics, entanglement has been recognized as one of its most puzzling features [1,2]. During the last few...

Measuring of the size and structure of the labour force in rural areas in Poland causes many difficulties. In particular, it refers to the population working in agriculture. It results from different data obtained from different statistical sources, from high dynamics of changes taking place in the Polish agriculture as regards the labour force, a high rate of older people working in agricultur...

The most common machining methods in machining are turning, milling, drilling and grinding. Significant studies are conducted in machining industry and academic circles in order to measure the cutting force during these processes. This study includes a review of these studies, a categorization of similar ones and detailed information about measurement systems. Through the review of studies, we ...

This thesis presents methods for comfortable sleep measurement at home. Existing medical sleep measurement systems are costly, disturb sleep quality, and are only suited for short-term measurement. As sleeping problems are affecting about 30% of the population, new approaches for everyday sleep measurement are needed. We present sleep measurement methods that are based on measuring the body wit...
